Crystal structure of dicaesium strontium hexa-cyanidoferrate(II), Cs₂Sr[Fe(CN)₆], from laboratory X-ray powder data.

ABSTRACT: Ferrocyanides with general formula A ^I _xB ^II _y [Fe(CN)₆], where A and B are cations, are thought to accept many substitutions on the A and B positions. In this communication, the synthesis and crystal structure of Cs₂Sr[Fe(CN)₆] are reported. The latter was obtained from K₂Ba[Fe(CN)₆] particles, put in contact with caesium and strontium ions. Hence, a simultaneous ion-exchange mechanism (Cs for K, Sr for Ba) occurs to yield Cs₂Sr[Fe(CN)₆]. The synthesis protocol shows that K₂BaFe(CN)₆ particles can be used for the simultaneous trapping of radioactive caesium and strontium nuclides in water streams. Cs
